Why did my Co-Worker ask if I have a boyfriend?

I see him occasionally and we’ll say hi to one another whenever we see each other in the halls at the hospital. I notice him staring at me and he’s approached me a few times since I started working the job. Recently, I was walking a patient to the ER and it seemed like the guy was invested in our conversation and I noticed my co-worker looked back to observe the interaction.

As I’m leaving the ER I noticed my co-worker and he stops me. He mentions what do I get into after work and maybe I would know the spots in the area because of a guy that’s taking me out. I questioned him to ask where is this going and he mentioned he wanted to know if I had a boyfriend. I tell him “no” and he mentions well “that’s all he wanted to know”.

It was an awkward interaction and I decided to bring up the places that I go to which is church and we made a small talk until we went our separate ways.

I’m confused?
